Anatomical and Clinical Predictors of Valve Dysfunction and Aortic Dilation in Bicuspid Aortic Valve Disease [1]
The authors studied 852 adults with bicuspid aortic valves. The prevelance of three morphotypes was tallied. Relative fusion rates were: RL 72.9%, RN 24.1% and LN 3%. Additionally, 18.3% had no raphe. Aortic regurgitation was unrelated to morphotype. Aortic stenosis was more common in the RN fusion group and in the presence of a raphe. Seventy-six percent had ascending aortic dilation unrelated to morphotype but associated with valve dysfunction. Aortic root dilation was present in 34% and was more commonly associated with male sex and aortic regurgitation.
